Research On Roadside Safety Evaluation Technology Of Mountain Tourism Highway

Along with the vigorous development of tourism in China,the construction of tourist highway in mountainous areas has attracted more and more attention.However,with the increase of traveling passengers,the incidence of traffic accidents has also increased,in these traffic accidents,roadside accidents caused the most serious harm,and most of the research on highway side safety in our country is confined to the conventional highway.The research on the side safety of mountain tourist highway is relatively scarce,and the standard of roadside design of conventional highway can not fully meet the human nature of mountain tourist highway in Chemical and safety requirements.Therefore,it is of great theoretical and practical significance to carry out the side safety evaluation and construction of mountain tourist highway.Based on the current situation of mountain roads in China's mountainous areas and the characteristics of tourist highways,this paper analyzes the law of roadside accidents in mountainous roads from the factors affecting roadside safety,and obtains the main factors affecting roadside safety.Through the analysis of roadside safety influencing factors,the roadside safety evaluation model of mountain tourism highway is established.According to historical project data and literature review,preliminary evaluation indicators are selected,and the principal component analysis method is used to screen the evaluation indicators and quantify and classify the indicators.Finally,a scientific and feasible roadside safety evaluation index system is determined,and then the material elements are used.The extension principle is combined with the evaluation index system to establish a roadside safety evaluation model for mountainous tourist highways,which provides a scientific and practical method and design basis for roadside safety evaluation of mountain tourism highways.According to the proposed roadside safety evaluation model,an example analysis of the tourism poverty alleviation secondary road project in Duan(Duan'an section)of Hechi City,Guangxi Zhuang Autonomous Region is carried out,which shows the rationality of the model in evaluating the road safety of mountain tourist roads..Combined with the roadside safety hazards existing on the road section and the problems existing on the existing mountain tourist road side,the roadside safety improvement suggestions for the induction facilities,the roadside drainage side ditch,and the guardrail and pole facilities are proposed.Provide reference for the design and construction of tourist highways.
